"Life in Gaza Today" contains work commissioned by the Australian Major Issues and Theology Foundation, and has visited Wellington and Christchurch, with its final New Zealand stop in Dunedin.
Knox Church member Andrew Bradstock said the exhibition was an opportunity for the artists to "express what it's like to live in an occupied territory".
Dunedin Abrahamic Interfaith Group secretary Mai Tamimi, who will open the exhibit tonight, "burst into tears" when she first saw the paintings.
"It's very emotional. They take me back home straight away."
She moved with her family from Palestine to Dunedin in 2008 to study at the University of Otago and believed the marked difference between the two areas highlighted the "unfair and unjust" lives of children in her homeland.
The "purist and most honest" works in the exhibition were those of the children, who make up 50% of the Palestinian population, Mrs Tamimi said.
She hoped people would visit the exhibition and learn about everyday life in Palestine and join the push for aid and Government support.
"It brings the life here, so for a moment, a person can live the destruction, war, sadness and worry."
The exhibition opens tonight at 5.15pm. It will be open 10am-4pm until Wednesday, then from January 3-5.
